is made up of three angle bars,designatedrespectively by numerals 30, 31 and 32,"said bar being adaptedto-be held by rivets 34 to the inclined surfaces 24 and their upper ends fastened together and secured to the" pulley block 35. The bars 31 and 32 are held by means of rivets 36 to. the inclined faces 28 and their upperwends are fastened e p duced of such a constructlon as wlll be thoroughly braced to allow. the, same towithto the pulley block 35.

Cast brackets, designated respectively numerals 37 and 38, have'thr ee pairs of fingers, designated respectively bynumerals 40, 41 and 42, a detail of one; of said bars being clearly shown in. Fig. 8 of-thedraw ings, and which fingers 4l are adapted to; engage the angle bar 30, while the fingers 40f engage the angle bar 32 and thefingers 42 Said angle bars are ar theangle bar 31. I ranged with the intermediate angle bar 30 in an opposite direction from the angles off the bars 31 and 32 and, whenheld by the 'bracket members as showmiwill tend to thoroughly brace one another, and produce a:

beam which will withstand any strain which might come upon it incident to raising heavy objects. inforce the angle bars .will'preventi any. of

the same from being bent and, when made as shown and described, will slip on'the z'tngle portion ofthe bars and will be held securely in their clamping relation Twith-thebars.

This-provides means for reinforcing the angle bars withoutthe necessity of b'orlng .holes through the same which would tend tof weaken the bars. 1

H Plates 40 are bolted to. the opposite sides of the head and are apertured fort-he reception of the reel shaft 41 having handles 42 fixed there'to' and upon whichshaft a wind: ing drum 43 is mounted. A suitable cable 44 is adapted to wind upon said drum and passes over "a pulley 46 in the pulley block '35. The casting of said pulley block has a recess 47 formed thereima detail of which is shown in Fig. 9 of the drawings, and an opening through the bottom of said recess is adapted to receive the shank portion of the swiveledmember 48, the upper'end of which is flanged as at 49 and provided with agroove or raceway 50, cooperating with a. raceway 51 formed in the bottom'of snare. cess [about the central opening therein for 'lthe'reception of the ball bearingsl'5'2. "A

key 53 passes'through the aperturein the 55 .sliank portion 48 of said member and serves to hold the balls in their proper raceways.

An eye 54 in said member 48 is adapted to receive one end of the cable, 51s shown clearly in Fig. 1, and which cable passes about. a ,60 a hook5'8 is connected.
